Unveiling the Hidden Might of Bionics: Lessons Directly from the Natural World
Biomimetics, a fascinating scientific discipline, has its roots deeply entwined with the observations of Leonardo da Vinci, who intensely studied bird flight. This field, which develops technical innovations through systematic observation of nature, is considered the father of biomimetics today due to his groundbreaking work.
Biomimetics is an interdisciplinary field with numerous applications, from consumer technology to military applications. For instance, the octopus's ability to change skin structure and colour is being studied for potential use in camouflage functions. Similarly, the kingfisher's streamlined beak inspired the high-speed Shinkansen train's distinctive nose.
The adaptive method in biomimetics, called "Biology Push", involves direct observation of nature to develop products. This approach has led to the creation of a novel bio-adhesive, combining the properties of mussel threads and slime, which adheres to wet tissue and could replace sutures or staples in surgery.
On the other hand, "Technology Pull" is the opposite way, where a technological problem is the starting point for researchers to actively search for natural solutions. This method has resulted in the development of bionic materials like Velcro, which was inspired by the burrs that cling to clothing.
In the realm of electronics, neuromorphic computing aims to establish a computing paradigm that is closer to the brain's model, using algorithms that mimic swarm intelligence or spiking neural networks. Silk threads, known for their tensile strength and elasticity, are being used in recent experiments to develop flexible bioelectronics.
Nature's intricate designs can also be seen in architecture, with structures like the Eiffel Tower resembling the inner structure of a bone with its fine bars and hollow spaces. Honeycomb and bone structures, often found in nature, are used in architecture to add stability and optical accents.
The microscopically grooved skin of a shark reduces turbulence, a principle transferred to the rotors of wind turbines and aircraft wings to increase efficiency. Meanwhile, the African brush-tailed porcupine's scaly tail is being studied for its potential in developing agile rescue robots to maneuver through rubble landscapes.
In sensor bionics, technical systems are oriented on the functioning of biological senses. For example, cameras with cat eyes or "whisker" sensorics based on mammals' vibrissae have been developed.
Lastly, nature's self-cleaning properties have inspired the creation of self-cleaning lotus effect coatings. Even in the energy sector, jellyfish batteries generate power from ionic processes in soft structures, an approach that could enable implantable medical technology in the future.
In conclusion, biomimetics continues to unveil the wonders of nature and transform them into innovative technological solutions, bridging the gap between the natural world and human-made creations.
